Calibrating quantum hydrodynamic model for noble metals in nanoplasmonics
Qiang Zhou, Wancong Li, Zi He +2
Quantum hydrodynamic model (QHDM) has become a versatile and efficient tool for studying plasmonics at the nanoscopic length scale. Yet its application to noble metals has not been…

The Truncated Metallo-dielectric Omnidirectional Reflector: Collecting Single Photons in the Fundamental Gaussian Mode with 95% Efficiency
Wancong Li, Luis Morales-Inostroza, Weiwang Xu +4
We propose a novel antenna structure which funnels single photons from a single emitter with unprecedented efficiency into a low-divergence fundamental Gaussian mode. Our device re…
